IMPROVEMENT IN BARS FOR HORSESHOE-BLANKS.

Specification forming part of Letters Patent No. 153,443, dated July 28,1874; application filed June 2'2, 1874.

OAsE B.

To all whom it may concern Be it known that I, WILLIAM W. LEwIs, ofCincinnati, Hamilton county, Ohio, have invented certain Improvements inBars for Horseshoe-Blanks, of which the following is a specification:

My invention relates to a crease in bars for horseshoe-blanks, and is animprovement upon an invention with the same title for which I havecompleted my specification, preparatory to applying for Letters Patent.It consists in forming the crease with an inwardly-beveled bottom, so asto give the creasing tool or roll, that is afterward to form the deepnail-crease, a draw, thereby keeping it in the proper line, andpreventing it from going out of its course.

In the drawings, Figure 1 is an elevation of a bar for horseshoelanks,showing my invention. Fig. 2 is a cross-section of the same, showing theinward bevel of the bottom of the crease.

A represents the bar, and a the guidingcrease, the bottom of which isbeveled toward the center of the bar.

In rolling horseshoe-blanks to form the deep nail-crease by means of theroll, it is difficult,

in practice, to keep the iron in the exact line so as to make thenail-crease in the proper place, especially when the guiding-crease is aright angle, or an obtuse angle. I obviate this by giving theguiding-crease, when the iron is rolled, a beveled bottom, so as to makethe angle about eighty degrees, instead of ninety degrees. Thus, whenthe bars are atterward rolled for the nail crease, there is a draw orbite given to the creasing-roll, which keeps the iron in position, andgreatly facilitates the work; also, when the bars are worked up by hand,the beveled crease furnishes a draw to the creasing-tool of the smith.

The bottom of the line or crease might be fluted, so as to accomplishnearly the same effect, though not as advantageously.

I claim In a bar for horseshoe-blanks, the guidingcrease a, when madewith the bottom beveled inward and downward, substantially as and forthe purposes described.
